UNITED STATES PATENT FFICEQ I WATER-MOTO R.

SPECIFICATION forming part of Letters Patent No. 227,307, dated May 4,1880.

Application filed March 2, 1880. (No model.)

To all whom it may concern:

Be it known that I, W'M. E. SEELYE, of Anoka, Anoka county, and State ofMinnesota, have invented a new and Improved Water-Motor; and I do herebydeclare that the following is a full, clear, and exact 'descrip-, tionof the same, reference being had to the accompanying drawings, formingpart of this specification, in which- Figurel is a section through theline as a; of Fig. 2, and Fig.2 is a section through the line y 51 ofFig. 1.

My invention relates to an improved watermotor constructed on thegeneral principle of a rotary engine, in which two compartments arearranged side by side, with a partition intervening, and in which thesliding pistons in the piston-wheels in the two compartments arearranged at right angles to each other.

My invention consists in the improved arrangement of the piston-wheelsand mode of connecting them together upon opposite sides of thepartition for simultaneous movement, as hereinafter fully described.

In the drawings, A A represent the two sections of the motor-case, whichare clamped together by bolts to upon a central partition, B, whose edgeis flush with the exterior of the case. Each one of the sections A A ofthe case is recessed, so that one of its parts, b, forms the head, andthe other part, c, the periphery, of the cylinder.

C is the drive-shaft of the motor, which shaft extends throughstuffing-box d in the heads b, and carries inside the case the twopiston-wheels D D. Each of these piston-wheels is slotted diametricallythrough to receive the sliding pistons E E, arranged at right angles toeach other, while the piston-wheels have upon each side of the slotshubs e e and e e, to give the requisite strength. One of thesepiston-wheels, D, is fixed rigidly to the shaft by a pin, while theother piston-wheel, D, is loose thereupon.

The opening in the central partition, B, is made large enough to receivethe abutting hubs e and e of the two piston-wheels, which hubs areconnected at this point for rigid revolution by two steady-pins, g g,which pins are fixed to one of the-hubs in parallel position with thecentral shaft, and enter corresponding holes in the other hub, to causeboth pistons to revolve together. This construction permits the twopistons to be rigidly connected upon opposite sides of the middle par 55tition, and yet allows them to be readily separated when necessary.

In arranging the several parts of the motor the piston wheel shaft isarranged eccen trically within the case, which latter is upon its innersurface elliptical, so that the pistons touch the inner periphery of thesame during their entire revolution.

Fis the inlet to the cylinder, and F the outlet, the inlet-pipe being inpractice, preferably, bifurcated, so as to feed both compartments of themotor. The piston of each compartment is provided at its ends withspring packing-blocks 1', while the piston of one compartment isarranged at right angles to that of the other, to render the action moreuniform.

For packing the sides of the pistons and piston-wheels, brass or othersoft-metal plates G G are arranged upon the outer hubs of 7 saidpiston-wheels next to the head portion 1) of the case, and are adjustedto the said pistons and piston-wheels by set-screws h h. A packing, H isalso fixed in the periphery of the cylinder between the inlet and outletpoints. This packing is formed with a rounded hinge or abutment at oneend, and its other end is adjusted to or from the pistons by aset-screw, j.

The action of this water-motor is in the main similar to that of anyrotary engine constructed on the same general principle-4. 0., the waterenters at F, and, operating against the face at of the piston, forcesthe pistonwheels and shaft around, driving the water in front of itthrough the outlet F, until the opposite end of the piston is brought infront of the inlet, the piston meanwhile having a longitudinally-slidingmovement.

I do not claim this generalarrangement of 5 eccentric piston-wheels andsliding pistons,

nor yet the duplicate arrangement of piston in a two-compartmentcylinder, as these have been heretofore made use of but What I claimis-- In a rotary motor or engine, the combination, with atwo-compartment case havinga partition within, of a drive-shaft carryinga rigid piston-wheel and a loose one provided with hubs, as described,with the hubs abutting in the planeof the central partition and con.- 10neoted for rigid revolution together by pin and sockets, as described.
